it would if the contacts were bad in pressure switch seen many that were but i know this one is working right it keeps running eaven when it is unpluged so it is defently somthing else keeping it on.

well found it it was a broken ground wire going to the relays from the pcm. i guess the pcm uses the ground wire to turn on and off the compressor. Dont know but it works now.
